I've got a Workhorse also. Yes, it certainly has power - no problems in the Rocky Mountains - passing 40' diesel pushers on the hills while towing. However, my wife gets upset when, at a stop light, I open my window and challenge the guy in the Corvette next to me to drag to the next lights. (just kidding) I've not needed any major service...just oil changes and those are easy. I did change out a fuel filter but was able to mail order the exact filter needed. However, I am now on a discontinued chassis - so I worry about facing parts shortages. So far, though, this has not been an issue.
